The concept of light speed being constant is puzzling to me. For instance, if a space vehicle is moving through space at near light speed (~c) and emits a light ray at speed c, does the light ray move away from the vehicle at speed c or is the separation speed (c - ~c) ? (Ignore constaints that would prevent the vehicle from achieving near light speed) Also, what would an observer see - maybe, the light ray and vehicle moving at almost the same speed c and ~c ?
